Migrating from jQuery to React

Winner: Draw

Prompt Used:

"Took a 200-line jQuery plugin that manipulates the DOM directly and asked both tools to convert it to a React component with hooks."
Result A:Cursor tried, but the conversion felt clunky. The component worked, but it still had some jQuery-style thinking in the React code.
Result B:I was impressed by Tabnine's attention to subtle details.

Analysis: From an industry perspective, Cursor serves professional users who require deep Coding capabilities, particularly around Best-in-class codebase indexing. Tabnine caters to Coding practitioners who value Runs locally (Private). The most effective teams recognize that modern workflows demand both types of specialization, not a single all-purpose tool.
